Pneumatic Overpressure Conveying of Bulk Goods

Pressure conveyor systems are similar to their vacuum counterparts, but work with overpressure. The bulk materials are blown along pipelines to their destination, greater pressure differentials are possible so heavier products such as sand, gypsum and cement may be transported. Overpressure conveyor systems are efficient, economical and reliable, but the products conveyed should be inert to oxygen. For this reason, pneumatic overpressure conveyors are rarely used in the food processing industry.
